i have SL4 application which used rich text box , the output of the richtextbox was saved in the database. but in silverlight 5 the output format has changed , due to which our silverlight 4 application is breaking , because when it loads we get an exception
"'Cannot set unknown member 'System.Windows.Documents.Paragraph.CharacterSpacing'.' Line number '1' and line position '283'."
later we saw the silverlight 5 rich text box and we found that there is a new format .
this is effecting us on live envirnment . whats the solution ? and also suggest some ways such that this wont happen when silverlight 5 comes in .
i have seen the silverlight 5 release document & i dont see this issue as a breaking change .
